To all whom it may concern:

Be -it known that .l, GEORGE WASHINGTON JACKSON, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal Sh.eetlilin.g; and I do hereby declare that the following is a full, clear, and exact descriptioli thereof, reference being had to the 0 accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in metal sheet piling used as retaining walls for 1.3 coilerdams or su iporting the earthen walls of texcavations, an refers more specifically to that kind of sheet piling comprising alternate sections of rolled metal bars or shapes which are constructed and arranged to have laterally interlocking, longitudinally guiding conv nection in such manner that each section, as

it is driven, is guided into place by its in.- terlocking or guiding engagement with an already driven adjacent section.

The invention consists in the matters hereina-fter set forth and more particularly pointed out in the appended claims.

Among the principal objects of my invention is to provide a construction in metal sheet piling of such character as to assure waterproof joints between the sections or units of the piling, and thus prevent leakage of water through a retaining wall constructs of such sheet piling. Other objects of the invention will appear from the description WillCi'l follows:

As shown in the drawingsz l igzuro 1 is a perspective view of the mitrudinp upper ends of a plurality of interlocked sections or to units of sheet piling made in accordance with my invention. Fig. 2 is a fragmentary horieontal section thereof.

trate means for preventing the bolts, used to hold together the members of the piling, from turning. Fig. 5 is 2. horizontal section, similar to Fig. 2, illustrating a modification. lli'igs. 6 and 7 are pers eetive views of parts of one of the sections 0. the piling, showing an other form of means for preventing the holding bolts from turning.

' .The sheet piling herein shown as embodying my invention embraces alternate sections or units which may be designated as simple and com onnd sections, one comprising a single rolled metal shape or bar and the other two rolled metal shapes or liars fastened to- I-beams.

Figs. 3 and 4 illusgether by bolts or the like, and providing between the two members, longitudinal spaces to receive interlocking parts of the single or simple sections'of the piling, thereby provid ing guiding means to guide each section, as it is driven, fronr'an already driven adjacent section.

The simple section of the sheet piling here in shown comprises an I-beam 10, while the compound section comprises two channel directed toward each other, but separated by longitudinal spaces to receive'the webs of the The two members of the compound section are secured together b bolts 13 13 which extend between and t rough nel bars. The flanges 15 15 of the E-beams IOoccu y the spaces inclosed'by the connected c iannel bars, the oblique inner faces 15 15 fitting the oblique faces of the flanges 12 12 of" the channel bars. The bolts by which channel members of the compound sections are secured together may consist of ordinary machine bolts. They are provided with "the usual heads 16 16 and nuts 17 17, the latter en aging bo ts. baid bolts extend through the marginal parts of the webs of the channel bars. 1 In accordance with one feature of my invention, means are provided to prevent said bolts from turning as .the nuts are being tightened or loosened. As shown in Fi s. 1

to 3 inclusive this is effected by the coop oymont of plates 20 which fit against the lateral, exterior faces of the webs of the channel bars and are )rovided Withopening 21 re istcring with t 1e bolt openings in said wens. Said plates 20 are formed at the sides of the bolt 0 enings with laterally extending lugs 22 which engage the heads 16 of said bolts 11) a manner to prevent the bolts from turning. The said lugs are formed by metal. struck up from the body of the plates. As showrfin Fig. 3 thc'lugs are located at the lateral sides of said openings, while in Fig. 4 they are located at the top and bottom of said openings.

In Fig. 6 I nave shown two narrow bolt holding. olates 23, which take the place of the single plate 20 of the previously described construction. Said narrow plates are provided with bolt head engagin lugs 22 made like and performing the same unction as the lugs of the first described plates. in Fig. 7 I have shownanother mode of preventing the bolts from turning, comprisingangle bars 24 bars 11 11 arranged with their flanges 12 12 the screw threaded ends of thebolt openings in the webs 14 14 of said chaniio - latera y from the faces 0 2 assess riveted to the exterior, lateral faces of the webs of the channel bars and arran ed in an allel pairs, a bar of each pair being ocate' on one side of each vertical row of bolt openings of said web.

The bolt holding plates referred to serve, in addition to their function of holding the bolts from turning, as stiffening plates to stren then the channel bars, thus permitting the c annel bars to e made of somewhat li hter metal when this construction is emp oyed. -The strengthening feature is somewhat emphasized in the bolt retaining or holding means shown in Fig. 7, embracin the an le bars 24, the flan es of which exten i the webs and constitute stifi'ening ribs.

In Fig. 5 is shown bolts 25,\ior connecting together the members of the compound sections, which. are provided with square shank portions 26 that enga e angular openings in the adjacent webs of the channel bars. This form of bolt and its interlocking connection with the channel bar permits the omission of the bolt holding means hereinbefore described, and is more specially adapted to lighter sheet piling.

eferring now to the construction by which watertight joints are provided be tween the several sections or units of my improved sheet piling, which construction constitutes the principal feature of the present invention, the same is made as follows:

30 30 designate elongated cores, made of wood or like material, which occupy the spaces between the webs of the channel bars or the compound sections. Said cores extend from end to end of said com ound sec tions and are made of a width to ii the s ace between the webs of said channel bars. hey are shown as made of elongated cross section, the greater length being in the direction of the length of the holding bolts, and are made narrower than the s aces between the two parallel rows of holding bolts of eachcompound section or unit.

e cores are placed between the channel bars of the com ound sections before the nuts of the holding liolts are turned to their final tightening positions. Thereafter the said nuts are tightened on the bolts and the pres sure due to such tightening has the ell'ect oi springing the marginal parts of the webs of said channel bars inwardly toward each other and of tlosely pressing together the inclined contacting faces of the flanges of the channel bars and I-beams, Under circumstances where practicable, the nuts of the holdin ibolts, of the compound sections are not ti litened until the simple sections interlocked therewith are driven and the cores are in place, thus permitting the sections to be readily interlocked and driven. The said cores, while advantageously made of wood, may be made of other material found suitable for this purpose. An advantea wood or hire fibrous material is th t cc of water therewith serves to expat ti cores, which has the effect to spring gamete of the bars outwardly and to press L119 flanges of the interlocked units together for struction, except as herein after made the subject ofspecuic claims.

I clann as my mvent1on:

1. Metal sheet piling comprising alternate units, one of which is a compound unit and. having inwardly directed longitudinal guide flanges, bolts extending through the mem- I bers of the compound units adjacent to the side margins thereof to hold the same together, and means between said bolts coasting with the bolts, when the nuts of the bolts are tightened, to press the flan ed mar insof the members inwardly tower each other.

2. Metal sheet iling comprisin alternate units, one of whic is a cor'npoun unit, and having inwardly directed, longitudinal guide flanges, bolts extending through the members of the compound unit near their margins to hold the same together, andcores occuin the s ace between the members of o P said compound unit and made of awidth less than the distance between said bolts.

3. Metal sheet-piling comprisin alternate units, one of which is a compouns unit'and having inwardlf directed longitudinal guide flanges, bolts extending between the incinbers of the compound unit near their margins to hold the same together and wood cores occu in the s )ace between the members of salt compound unit and made of a width less than the distance between said bolts.

4. Metal sheet pilin simple and compoun sections consisting of Lbeams, and the compound sections consisting of channel bars arranged with their flanges directed inwardly toward each other and held together by bolts comprising alternate extendingthrough their marginal parts, and

longitudinal cores extcndhig between the sections, the simple webs of said channel bars and made of awidth less than the distance between said bolts.

5. Metal sheet piling comprising alternate units, one of which is a compound unit composed of plates fastened to ether by bolts and formed at their marginal parts to afford laterally interlocking and longitudinally guiding engagement with adjacent units, said bolts extending through said plates of the compound unit and having angular arts which interlock with angular parts 0. the plates to prevent rotation thercoi'.

comprising cha-nnel bars arranged with their 6. Metal sheet piling comprising alternate through which they pass to prevent bolts simple and compound units, the simple units from turnin when the nuts thereof are comprising Lbearns and the compound units tightened orioosened. c r

In testimony, that I claim the foregoing as my invention I altix my signature in the flanges directed toward each other, said 1 channel bars being held together by bolts extending through the webs thereof, and the August A. D. 1907.
